| خلاصه مقاله | Nanosciences covers a vast majority of devices derived from biology, engineering and basic
sciences which contain nanovectors for the drug delivery system in anticancer drugs. There have
been available nanoparticles with various characteristics for optimal drug delivery e.g. for
increasing their stability in the circulation system and targeted delivery to the tumors by taking the
advantage of enhanced permeability and retention effect near the tumor tissue. Evaluation of the
mechanisms and therapeutic effects of nanoparticle-based Mammalian mechanistic target of
rapamycine (mTOR) modulation can be useful in developing safe in treatment of cancer. mTOR
is a conserved serine/threonine kinase in the cellular PI3K/Akt/mTOR signaling pathway.
This pathway is modified by cellular alterations such as level of energy, growth factors,
stresses, as well as the increased environmental level of cancerous cytokines. In general,
increase of this kinase protein function is seen in various types of cancers, especially in
cancer stem-like cell. Additionally, activation of this pathway in the most common cancers
like nervous system is in consideration. Recent studies have shown the relationship
between different cellular signaling pathways and genetic mutations, that involved in the
cancers, with mTOR pathway. Based on previous studies, different treatments like surgery,
chemotherapy, radiotherapy, aren’t more effective and have some side-effects. Therefore,
the researchers are trying to find better ways to treat cancer. One approach to this aim is
about the essence of understanding all of molecular pathways, proteins and mutations
involved in cancers. To reach a good efficacy, high distribution and accepted dispersing of utilized
drugs in control of mTOR signaling pathway, nanomedicine has been defined as a dramatic
manner. In clinic to establish a new mTOR deregulation in human diseases, hereby, we address
the recent progress in the field of nanoparticle-based mTOR targeted therapy. |
